Review and update of the criteria for objective cognitive impairment and its involvement in mild cognitive impairment and dementia

CONCLUSIONS: From an initial search of 1954 articles, 17 were eventually reviewed. The original diagnostic criteria required low scores in one neuropsychological task, biasing MCI towards the amnesic type. Subsequent criteria expanded the number of tests in the battery, which allowed classifying MCI into amnesic and non-amnesic type, as well as into 'single-' and 'multiple' subtypes. Since increasing number of tests affected the probability of diagnostic errors, subsequent criteria incorporated normal variability for the identification of objective cognitive impairment. This work offers a critical review of the strengths and weaknesses of different diagnostic criteria for objective cognitive impairment, for use in both clinical and research settings on MCI and dementia.PMID:33851718 | DOI:10.33588/rn.7208.2020626
